Hi,

can I safely use GPTs within a GEOM_MIRROR?

I created a new mirror and then used gpart to create additinal
partitions. dmesg gives:

the secondary GPT header is not in the last LBA

As far as I read by now it seems safe to ignore that message but I want
to get sure.

Or are mirrored GPTs only safe when using ZFS?

Thanks, Helmut
